Laser micro machining includes a series of processes for various materials, including metals, plastics, ceramics, glass, diamonds, sapphires, etc. Due to scale or complexity, many of these processes cannot be realized by traditional methods. Machining small and fine shape and structure, achieving the minimum thermal effect and high precision, these precise and fine requirements are critical to the success of applications.

The products in the electronics, medical, solar and battery industries are constantly innovating, and the design is increasingly small, precise and complex. The tolerance for error rate is low, and precise and repeatable micro processing is required. Due to the high complexity and value of manufacturing these products, laser processing systems must provide high repeatability, stability and productivity while maintaining excellent quality.

In order to achieve high quality of fine processing and ensure minimum thermal damage, short wavelength and short pulse lasers will be used in production. They require peak power, inter pulse stability, and excellent beam quality to achieve consistent results and provide fine detail. The XY gantry and scanning galvanometer are required to have excellent precision positioning performance. The fast motion control provided by the scanning galvanometer is necessary to make full use of the laser with higher repetition rate and improve the productivity.
